Is it possible to shield an object from the effects of magnets? Can magnetic force be directed with shielding?
I know You Can shield objects and electronics/electronic signals & wires from interference, but that's electromagnetic. I'm talking about a regular neodynium rare earth magnet. Can it be done with a substance, like lead, as opposed to a "powered" or electrically induced counterforce?
Sure. You can concentrate magnetic flux in a shield of a very high-permittivity material (a so-called "mu-metal") and thereby direct most of it around something inside. Alternatively, you can put your object-to-be-shielded inside a superconducting cavity: superconductors oppose the introduction of magnetic fields very efficiently.
